CAP FOR FUSES.

SPECIFICATION forming part of Letters Patent No. 699,586,dated May 6,1902.

Application filed November 19,1901. Serial No. 82,909. (No model.) 7

To all whom it may concern:

Be it known that 1, CHARLES EDMOND STE- ,VENS, a citizen of the UnitedStates, residing at Lovelooks, in the county of Humboldt and describedand as State of Nevada, have invented certain new and usefulImprovements in Caps for Fuses;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in caps for fuses, and has for itsobject to provide a cap with means to prevent a fuse from turning ortwisting andagainst accidental displacementwhile within the cap and toprevent premature explosion of the powder within the cap by too greatapressure of the fuse upon the powder.

My invention'consists'of a fuse-cap constructed substantially as hereinshown and particularly pointed out in the claim.

In the accompanying drawings, illustrating the preferred embodiment ofmy invention, Figure l is an elevation of. my improved cap; and Fig. 2is a longitudinal section thereof, showing a fuse in position.

In carrying out my invention I construct the cap of' a shell 1 having apointed end 2 and an opposite open end 3. The body portion of the shellnext to the open end isipreferably cylindrical and has prongs or. barbs4 out therein. Upon the interior of the shell, about midway between theends, isan ofise't 5. In employing my device premature explolindricalsion of the powder within the cap caused by too great a pressure of thefuse upon the powder, which happens either when the fuse is pushedwithin the cap or when the fuse after its insertion'within the cap istwisted or turned in tamping a blast or picking out one which has failedto discharge, is avoided.

In use an explosive is placed within the cap below the ofiset 5, andthen a fuse is inserted the desired distance, which, however,is limitedby the offset. 7 The prongs or barbs 4 are next forced inward to engagethe fuse to prevent it from turning or twisting and against accidentaldisplacement. It is obvious that the ofiset will limit the insertion ofthe fuse, and thus prevent it from pressing against the powder withinthe cap,which would beliable to cause it to explode. The pointed end ofthe cap permits its ready insertion Within a blast to be dischargedwithout first making a hole therefor.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-.

A cap for fuses, comprising a shell having a body portion, apointed end,an ofiset on its interior to limit the insertion of a fuse therein, andprongs struck up from said cy portion to engage a fuse, substantially asset forth. I

In testimony whereof I affix my signature in presence of two witnesses.
